Parental culpability for juvenile delinquency has permeated social welfare thought and practice throughout U.S. history. This article presents a case study of one Midwestern municipality's efforts to create a training school for parents as a remedy for delinquency in the 1940s. The case study illustrates how city leaders attempted to put theory about delinquency causation into practice by forging a collaborative intervention strategy among various community partners including public schools, social welfare agencies, and law enforcement. In light of the case study, this article examines historical and contemporary efforts to punish parents of juvenile delinquents.
